ANTISKID DEVICE FOB. SHOES.

Application filed January 30, 1922.

T 0 all whom it may concern Be it known thatl, GRANVILLE LEWIS SwnNY, a citizen of the United States, and a resident of Piqua, in the county of Miami and I State of Ohio, have invented certain new and useful Improvements in Antiskid Devices for Shoes, of which the following is a specification.

My invention relates to anti-skid or antislipping devices for shoes, and it consists in the combinations, constructions and arrangements herein described and claimed.

An object of my invention is to provide an attachment which can be readily applied to or removed from a shoe and which, when in applied position, will engage a surface traversed in such manner as to prevent the slipping of a wearer of the shoe upon a wet or slippery surface.

A further object of my invention is to provide an attachment of the character described which is adapted for application to shoes of various sizes and which will engage with a shoe in such manner as to remain thereon without injuring or marring the finish of the shoe.

A still further object of my invention is to provide an attachment of the character described having portions arranged between the shank of the shoe and a surface and exerting a tension on the arch, thereby stifiening the latter and tending to prevent sagging of the shank of the foot of the wearer.

A still further object of my invention is to provide an anti-skid or anti-slipping attachment for shoes which will engage the surface traversed with a yielding action, thereby precluding the possibility that shocks and jars may be coimnunicated to the foot of a wearer.

Other objects and advantages will be apparent from the following description, and the novel features of the invention will be particularly outlined in the appended claims.

My invention is illustrated in the accompanying drawings, forming a part. of this application, in which Fig. 1 is a view showing a shoe equipped with my invention and Fig. 2 is a bottom plan view of the shoe and attachment shown in Fig. 1.

In carrying out my invention, I make use of a single piece of spring wire which is bent. intermediately to provide a loop 1 adapted to embrace the lower part of the traversed Serial No. 532,538.

upper of a shoe 2 and to engage with the heel 3 of the shoe at the sides thereof. The sides of the loop 1 are bent vertically into V or U-shaped spring portions a and 5 at opposite sides of the heel portion of the shoe, the apex of the spring portion a terminating adjacent to the plane of the lower side of the heel and the apex of the spring portion 5 terminating at an appreciab e distance above the heel. The sides of the loop are then bent toward each other at 6-6 in underlying relation to the shank portion 7 of the sole of the shoe and contiguous to the front side of the heel 3, meeting at 8 sul stantially at the longitudinal median line of the shoe and being twisted to extend in twisted relation along the longitudinal median line of the sole of the shoe for an appreciable distance from the front side of the heel. The end portions of the wire are then bent laterally of the twisted-together portions, as at 9-9 and are formed into helical spring portions 10-10 having the largest convolution thereof contiguous to the shank portion of the sole of the shoe at opposite sides of the twisted-together portions and terminating in points 1111 depending slightly below the plane of the bottom faces of the heel and sole of the shoe.

From the foregoing description of the va rious parts of the device, the operation thereof may be readily understood. T he V-shaped spring portions of the loop 1 will yieldingly press against the upper of a shoe and the heel thereof in such manner as to maintain the attachment upon the shoe in the position in which illustrated and to permit of the facile application of the attachment to the shoe. An attachment having a loop of a given size will be suitable for use with shoes of various sizes and to ad pt the attachment for use with shoes of even larger or smaller sizes, it is only neoesary to vary the angle of divergence of the sides of the V-shaped clamping portions 4: and 5. The ends or points 11 of the helical spring portions 10 will engage with a slippery surface, such as a wet or icy pavement, and will hold the foot of a wearer against slipping, without interfering in. any way with the movement of the wearer in walking. Moreover, the shank portion 7 of the shoe will be yieldingly urged upward when the foot is placed upon a flat surface, as in walking, thereby precluding the sagging ofthe arch of the shoe and extending the life of the shoe in service of the term of the device disclosed herein which fairly fall within the scope of the'appended claims.

claim l. A. device of the character described comprising a helical spring portion terininatin at its smaller end in a point, and means tltor releasably securing the helical spring portion to the bottom of a shoe to l 'on the largrer end of the helical spring portion underlyingrelation to the bottom of the shoe and the point of the helical spring portion in a plane below the plane or the sole of the shoe.

A device of the character described comprising; a pair 0t helical spring: portions, each terminating at its smaller end in a point. and means connecting with the larger end of said helical portion for releasably securing the latter to a shoe in such manner as tooosition the larger end of the helical portion in contiguity to the shank portion of the sole of the shoe, the helical portion beinp; of such length that the point thereof depends below the plane of the sole of the shoe.

The combination with a shoe. of a demountable attachment therefor said attachment comprising a loop portion embracing the shoe at the sides of the heel and above the heel thereof, and helical spring portions carried by said loop in advance of the heel with the lereer ends thereoi contiguous to the lower side of the shank portion ot the sole ot the shoe and the smaller ends of the helical portions terminating below the plane or": the heel ot the shoe.
